fall-over basically tears down the peering session as soon as reachability to the peering address is lost. It is event-driven rather than timer based session deactivation. The issue with the feature is that there is no delay/dampening method and so a momentary loss of reachability can result in the peer(s) being torn down. - -- ========= bep -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlE+D08ACgkQE1XcgMgrtyZOswCfYk3yinAkfBgFTH/mpyDpK0aD 9wEAnAkMIrFe6+GmsFyHrNhK11U7qXJL =IYuT -----END PGP SIGNATURE----- _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
